CONTROLLING PEPPER WHITE MOLD DISEASE USING SOME AGRICULTURAL PRACTICES

Abstract

ABESTRACT: White mold disease of pepper that cause about Sclerotinia sclerotiorum, is considered one of the most important disease which infected pepper. The disease symptoms were beginning with dark-green, water-soaked lesions on stems and fruits. Lesions expand rapidly under most conditions, and the affected parts become a watery rotten mass covered by white fungal growth. After several days, the fungal growth on external plant surfaces plant forms a white. Which develops a black exterior and white to beige interior several days later moldy growth and black sclerotia are characteristic of this disease, that cause also to a very loose in the crop. Efficacy of application of some agricultural practices, i.e. plant density, breeding of seedlings, irrigation, fertigation and transplanting date on control of white mold disease that caused by Sclerotinia sclerotiorum was examined under greenhouse conditions during summer seasons (2016/2017) in Belco Egypt Co. Farm Sadat city, Menoufia governorae. Three distances between the transplants were investigated, in addition to, two methods were used in the breeding of pepper plants (Orngery RZ F1 hybrid), three differnt levels of irrigation, three levels of fertigation, plant density and three transplanting date were also studied.
